Flammability range of methane
WebHigh concentrations of methane in water wells can accumulate in confined spaces and act as an asphyxiant or become flammable. These dangers can be mitigated through enhanced venting of the well casing or venting confined spaces (like basements) and removing any ignition sources.

Table 1: Gas ... t shirt louisvilleLower flammability limit (LFL): The lowest concentration (percentage) of a gas or a vapor in air capable of producing a flash of fire in the presence of an ignition source (arc, flame, heat). The term is considered by many safety professionals to be the same as the lower explosive level (LEL). At a concentration in air lower than the LFL, gas mixtures are "too lean" to burn. Methane gas has an LFL of 4.4%. If the atmosphere has less than 4.4% methane, an explosion cannot o… t shirt louisianWebFeb 15, 2024 · In the pure methane scenario, the flammability limit for methane is 9%–17%, and the VDP region is 9%–15%.
